6. Your problem:

Hello,

I just started using SIP Server, coming from OpenSIPS. I'm running into a problem where I need to setup an alias, have it forward to a registered user, but keep the to field as the alias.

Example:
Call comes in to 444-555-6666 which is an alias for 111-222-3333

The header currently reads as follows: The header needs to look as follows: Our PBX determines what extension to send the call to based on the To field. So we need the alias to be displayed in the to field and the registered number to be displayed in the INVITE request-uri. Does anyone know of a way to do this?

The current dial plan rule is as follows:

Matching Pattern:$request=^INVITE
To=sip:(.+)@
$alias.lookup("%1")=(.+)

Deploy Pattern:
To=sip:%2@

Thanks,
Brian[/u]

Matching Pattern:
$request = ^INVITE
$getUri(To) = sip:(.+)@(.+)
$alias.lookup("%1") = (.+)
$regUri("%3") = (.+)

Deploy Pattern:
$request = INVITE %4 SIP/2.0
To = sip:%1@%2


Modify it as you want.

Thanks for the fast reply Taitan.

It doesn't quite work... It throws back a busy signal, but when I $log out all of the lines it gives me the correct info. It almost looks as if the Invite isn't actually leaving the SIP Server. When I look at the logs in the PBX that should be receiving the call, it doesn't show any communication from the SIP Server.

Here is the output from the SIP Server log:
There is no info on the PBX log to show.

Here is exactly what the rule states:
Matching Pattern Deploy Pattern By the way, I did remove the To=sip%1@%2 in the Deploy Pattern leaving only the invite to see if it would make a difference and it didn't.

Any thoughts?

Thanks again for the fast response,
Brian

Add $regAddr in the Matching Pattern and add $target in Deploy Pattern


Matching Pattern:
$request = ^INVITE
$getUri(To) = sip:(.+)@(.+)
$alias.lookup("%1") = (.+)
$regUri("%3") = (.+)
$regAddr("%3") = (.+)


Deploy Pattern:
$request = INVITE %4 SIP/2.0
To = sip:%1@%2
$target = %5
$log=------------------------------
$log=debug: Hit rule 3 (Convert_Alias)
$log=debug:INVITE %4 SIP/2.0
$log=debug:To=sip:%1@%2
$log=debug:TargetAddr=%5
$log=------------------------------

Thanks Taitan! That worked great.
